摘　　要：塔河碳酸盐岩是经过多期构造破裂和古风化壳岩溶共同作用的缝洞型油气藏,储集空间主要有溶洞、裂缝及孔隙三种类型,其特点是不规则形态和非均匀分布,储层非均质性极强,油水关系复杂。文章从排水采油原理出发结合H20井组地质背景、生产特征、连通情况入手对井组连通情况、见水特征进行分析,根据井组水侵规律认识,制定排水采油复合气水协同组合治理对策,实现井组复合挖潜,效益开发。Tahe carbonate rock is a fractured vuggy oil and gas reservoir which has undergone multi-stage structural fracture and paleoweathering crust karst.There are three types of reservoir space:karst cave,fracture and pore.Its characteristics are irregular shape and non-uniform distribution,strong reservoir heterogeneity and complex oil-water relationship.Based on the geological background,production characteristics and connectivity of H20 well group,this paper analyzes the connection and water breakthrough characteristics of well group,obtains the understanding of water invasion law of well group,and formulates the combined treatment countermeasures of drainage and flow regulating potential and gas water coordination combination,so as to realize the compound tapping potential of well group and benefit development.
